Unpacking and Checking the Equipment Unpack the radio carefully. We recommend that you identify the items listed below in the following table before discarding the packing material. If any items are missing or have been damaged during shipment, please contact the carrier or the dealer immediately. Supplied Accessories

Item Quanty 1 Radio 1 2 Antenna 1 3 Battery 1 4 Hand Strap 1 5 Charger 1 4 Power Adapter 1 7 Belt Clip 1 8 Instruction Manual 1

Getting started

Charging the Battery Plug the power adapter into the proper AC wall outlet and insert the DC plug in the charger base. The Red LED will flash for 4.5 seconds after it is first turned on. Insert the battery or the radio to be charged into the charger slot. Please turn off the radio before inserting it into the charger. Make sure the battery is in good contact with the charger terminals. When the red indicator is lit, the charger begins to charge the battery. After charging for about 3 hours, the red LED will turn OFF and the green LED will turn on indicating the battery has been fully charged. Only for NiMH battery on the first charge, please leave the battery in for two more hours after the green light first turns on before you remove it from the charger to achieve the best performance of the battery. Then you can disconnect the power adapter from the AC outlet. If the Red LED flashes quickly (0.2s on 0.2s off), this means the charging process has stopped because the charging temperature is too high or the battery has a problem. If that happens the charger enters a protective state and no more charge is delivered to the battery. Please stop charging in such situation and remove the battery from the charger.

Notice: The new battery is not fully charged in the factory, and needs to be fully charged when you use the radio for the first time. The radio is supplied with a standard battery manufactured by the factory.

The battery, after been in storage for a long period ,will not reach the full capacity till several charging and discharging (during use) cycles. Do not recharge the battery after it has been fully charged or it is partially discharged, otherwise it might affect the battery life or performance. Remove the battery from the charger after charging is finished. If the radio enters a low battery warning state, please recharge the battery. Do not use the radio in a low power warning state because it will affect the battery life and performance.

Installing/Removing the Battery Pack To install the battery, please place it into the groove on the top of the radio chassis about 5mm away from latch. If the radio has the belt clip installed, you will have to press one side of the clip to raise it and then slide the battery in proper position.

You can now access the current configuration of the radio by double clicking on the Radio information listed in the drop down menu on the left. Screen will show the configuration information similar to this:

The arrows point to the information you need to record. When you go to the CSI site, and select software for the CS750 you will see a listing of firmware updates. Below is a screen shot of the site as an example of what you will see.

According to CSI, if your radio is more than one firmware version older than the latest version, you DO NOT have to do the intermediate firmware updates, however if the CPS version (the programming software) is at a newer version than what you have, you need to perform the CPS Upgrade described in this document.

So for example, from the information shown at the CSI site, the latest configuration of a radio would be: Firmware Version: 1.01.03 Boot Loader Version: 2.01 So for this example, the information obtained from reading the information from the radio shows that the radio is at the current configuration, so no updates are required. If the radio had shown a firmware update listed in one of the earlier release dates, or a lower version of the Boot Loader, the radio requires an update. To determine the version of the CPS software you have, launch the CPS software, click on the Help located on the top menu ribbon, then click the About, you should see a pop up like below showing the version you have.

If the CPS upgrade is required, do the translate of your current code plug, it will create a new code plug with a slightly different file name. DO NOT attempt to load the translated code plug into the radio until you have completed the actual firmware updates. To aid in keeping things straight, I create a file folder on my computer to download the firmware updates to work out of.

Firmware Update Procedure Locate the FlashBurn file you downloaded. Should look something like the file below:

36

Double click on the file and it should launch. Your PC might ask if you want to Run, click to Run. Should see something like this:

Click on the A pop up window will appear to allow you to go to the folder that you stored the boot loader file. File will be something like, 750_bootloader_D2.01.bin. Note your version number at the end of the file might be different. Click on the file, and then click on Open, the file should then appear in the File Package dialog box of the FlashBurn program. Next follow the four steps shown on the FlashBurn program. Once the radio has rebooted, leave it connected to your computer. Next locate the firmware update file you stored. File should be something like CS750(2000)_Host_S1.01.03.20150825.bin. Note version number at end of file might be different. Click on the file, and then click on open, the file should then appear in the File Package dialog box. Click on the Flash button on the FlashBurn program. Once the download is completed, the radio should reboot. This completes the update process. Now that the firmware is updated on the radio, it might show not programmed when powered up. You need to reload the radio with the updated code plug you translated. With the radio connected to your computer, launch the programming software, and download the code plug.

CPS Upgrade When upgrading to a new version of CPS be sure to translate your code plug from the previous version. To do this, open the new version of the CPS. Do NOT open your code plug file. Click on “Tools” in the top menu ribbon bar. Select “CPS data Translate”. Pop of menu will come up, shown below.

Click on the “-“ button to the right of the Source file path box. Locate your code plug and open, it will show up then in the Source file path box. Do NOT type anything into the Destination file path box, instead just click on the Translate button, the file will be translated, and the new name will appear in the Destination file path. This will be the new code plug.

Programming Cable The programming cable for the CS750 plugs into the external microphone speaker jack on the side of the radio.

Trouble shooting No. Problems Solutions 1 The radio cannot be switched on or no

display after switched on Battery pack may not be installed properly. Reinstall the battery pack. Or Battery power may be insufficient. Recharge or replace battery pack.

2 The battery doesn’t last long after charging

The battery life is finished. Replace with new battery pack.

3 Cannot talk to or hear other members in your group

Digital: Make sure the CC, ID Time Slot is correct Analog: Make sure the signaling is set correct Or Beyond the radio efficient communication range

4 Other voices from non-group members are heard on the channel

Analog: Change the CTCSS/DCS tone, and make sure change the tone on all radios in your group

5 Communication range is too small 1. Make sure the antenna is well connected 2. Make sure the antenna is the originally supplied one 3. Check if the battery power is in the normal state 4. Ask you local deler to adjust the squelch level

6 Unable to Transmit 1. Make sure the PTT button has been pressed completely 2. Battery power may be insufficient, recharge or replace battery pack 3. Transmitting frequency has not been set on the channel and the radio has been remote killed

7 Noise to Load 1. Battery power maybe insufficient, recharge or replace battery pack 2. Beyond the sufficient communication range.
